Rosie uses her worthless slave as her seat while she does her nails.
She say him "hello" with the heel stiching in his chest, the she binds his hands, she wants him quiet and helpless.
She steps over him and decends on his face, with a little ass-shake she finds a comfty position for her derrier.
Now she does her nails and forgets the face-cushion under her... he is made for suffer under herr weight ;-)
Later in the clip, she changes her seating direction, may be she finds a better, more comfortable, position on him... or not...
Anyway, at the end she's again in the same way on him... time for lift her feet off the ground and giving him a fullweight ass-kiss.
